To a solution of 4-bromomethyl-3-nitrobenzoic acid (2.00 g, 7.69 mmol), benzyl alcohol (796 mL, 832 mg, 7.69 mmol) and 4-dimethylaminopyridine (9.4 mg, 77 μmol) in dichloromethane (5 mL) was added DCC (1.59 g, 7.71 mmol) and the mixture was stirred at ambient temperature for 3 h. The mixture was filtered and the solvent was removed under reduced pressure. The residue was purified by chromatography using a 0-30% gradient of heptane/ethyl acetate gave benzyl 4-bromomethyl-3-nitrobenzoate as an oil.
